Abstract
We describe a peculiar contralesional drawing disorder in three patients affected by focal brain lesions, who did not show signs of unilateral neglect at standard clinical assessment, including the star cancellation test. This picture, that could be termed selective constructional hemi-apraxia (CHA), could follow both right and left-hemisphere lesions and is observed in complex constructional tasks. Future studies are warranted to explore the clinical and functional implications of CHA and its boundaries with unilateral neglect and constructional apraxia.
